1 Safety and Regulatory Information
The product documentation helps you use the product safely and efficiently. Fol-
low the instructions provided here and in the Chapter 1.1, "Safety Instructions",
on page 7.
Intended use
The product is intended for the development, production and verification of elec-
tronic components and devices in industrial, administrative, and laboratory envi-
ronments. Use the product only for its designated purpose. Observe the operating
conditions and performance limits stated in the data sheet.
Where do I find safety information?
Safety information is part of the product documentation. It warns you of potential
dangers and gives instructions on how to prevent personal injury or damage
caused by dangerous situations. Safety information is provided as follows:
●In Chapter 1.1, "Safety Instructions", on page 7. The same information is
provided in many languages as printed "Safety Instructions". The printed
"Safety Instructions" are delivered with the product.
●Throughout the documentation, safety instructions are provided when you
need to take care during setup or operation.
1.1 Safety Instructions
Products from the Rohde & Schwarz group of companies are manufactured
according to the highest technical standards. To use the products safely, follow
the instructions provided here and in the product documentation. Keep the prod-
uct documentation nearby and offer it to other users.
Use the product only for its intended use and within its performance limits. Inten-
ded use and limits are described in the product documentation such as the data
sheet, manuals and the printed safety instructions. If you are unsure about the
appropriate use, contact Rohde & Schwarz customer service.
Using the product requires specialists or specially trained personnel. These users
also need sound knowledge of at least one of the languages in which the user
interfaces and the product documentation are available.

If any part of the product is damaged or broken, stop using the product. Never
open the casing of the product. Only service personnel authorized by
Rohde & Schwarz are allowed to repair the product. Contact Rohde & Schwarz
customer service at http://www.customersupport.rohde-schwarz.com.
Lifting and carrying the product
The product is heavy. Do not move or carry the product by yourself. A single per-
son can only carry a maximum of 18 kg safely depending on age, gender and
physical condition. Look up the maximum weight in the data sheet. Use the prod-
uct handles to move or carry the product. Do not lift by the accessories mounted
on the product. Accessories are not designed to carry the weight of the product.
To move the product safely, you can use lifting or transporting equipment such as
lift trucks and forklifts. Follow the instructions provided by the equipment manu-
facturer.
Choosing the operating site
Only use the product indoors. The product casing is not waterproof. Water that
enters can electrically connect the casing with live parts, which can lead to elec-
tric shock, serious personal injury or death if you touch the casing. If
Rohde & Schwarz provides a carrying bag designed for your product, you can
use the product outdoors.
Unless otherwise specified, you can operate the product up to an altitude of
2000 m above sea level. The product is suitable for pollution degree 2 environ-
ments where nonconductive contamination can occur. For more information on
environmental conditions such as ambient temperature and humidity, see the
data sheet.
Setting up the product
Always place the product on a stable, flat and level surface with the bottom of the
product facing down. If the product is designed for different positions, secure the
product so that it cannot fall over.
If the product has foldable feet, always fold the feet completely in or out to ensure
stability. The feet can collapse if they are not folded out completely or if the prod-
uct is moved without lifting it. The foldable feet are designed to carry the weight of
the product, but not an extra load.
If stacking is possible, keep in mind that a stack of products can fall over and
cause injury.

If you mount products in a rack, ensure that the rack has sufficient load capacity
and stability. Observe the specifications of the rack manufacturer. Always install
the products from the bottom shelf to the top shelf so that the rack stands
securely. Secure the product so that it cannot fall off the rack.
Connecting to power
The product is an overvoltage category II product and has to be connected to a
fixed installation used to supply energy-consuming equipment such as household
appliances and similar loads. Be aware that electrically powered products have
risks, such as electric shock, fire, personal injury or even death.
Take the following measures for your safety:
●Before switching on the product, ensure that the voltage and frequency indica-
ted on the product match the available power source. If the power adapter
does not adjust automatically, set the correct value and check the rating of the
fuse.
●If a product has an exchangeable fuse, its type and characteristics are indica-
ted next to the fuse holder. Before changing the fuse, switch off the instrument
and disconnect it from the power source. How to change the fuse is described
in the product documentation.
●Only use the power cable delivered with the product. It complies with country-
specific safety requirements. Only insert the plug into an outlet with protective
conductor terminal.
●Only use intact cables and route them carefully so that they cannot be dam-
aged. Check the power cables regularly to ensure that they are undamaged.
Also ensure that nobody can trip over loose cables.
●If the product needs an external power supply, use the power supply that is
delivered with the product or that is recommended in the product documenta-
tion or a power supply that conforms to the country-specific regulations.
●Only connect the product to a power source with a fuse protection of maxi-
mum 20 A.
●Ensure that you can disconnect the product from the power source at any
time. Pull the power plug to disconnect the product. The power plug must be
easily accessible. If the product is integrated into a system that does not meet
these requirements, provide an easily accessible circuit breaker at the system
level.

and usability. The R&S FSW provides the following outstanding key features:
●Unmatched phase noise
●Excellent dynamic range
●Up to 8.3 GHz analysis bandwidth
●800 MHz real-time analysis bandwidth with 2.4 million FFT/s, 0.46 μs POI and
500 MHz I/Q data streaming interface
●High sensitivity even at low frequencies
●High measurement rates and fast sweep times with sweep rates up to 1000
sweeps per second
●Multiple measurement applications can be run and displayed in parallel
●Easy and intuitive to operate via the large touchscreen user interface and opti-
mized user guidance

4. Check the equipment for damage.
If the delivery is incomplete or equipment is damaged, contact
Rohde & Schwarz.
4.3 Choosing the Operating Site
Specific operating conditions ensure accurate measurements and avoid damage
to the product and connected devices. For information on environmental condi-
tions such as ambient temperature and humidity, see the data sheet.
See also "Choosing the operating site" on page 8.
Electromagnetic compatibility classes
The electromagnetic compatibility (EMC) class indicates where you can operate
the product. The EMC class of the product is given in the data sheet under "Gen-
eral data".
●Class B equipment is suitable for use in:
– Residential environments
– Environments that are directly connected to a low-voltage supply network
that supplies residential buildings
●Class A equipment is intended for use in industrial environments. It can cause
radio disturbances in residential environments due to possible conducted and
radiated disturbances. It is therefore not suitable for class B environments.
If class A equipment causes radio disturbances, take appropriate measures to
eliminate them.
